Beautiful image of different microbes in CLED medium

This image results from a project called "Initiation to microbiology investigation" accomplished by young students, where they collected a sample from a table surface and by inoculation they put it in CLED (cystine lactose electrolyte deficient) medium. Beautiful colonies of bacteria and fungu... Read More

The pearly colonies

Yeast extract-mannitol agar (YMA), with the pH indicator bromothymol blue (BTB), is the medium used for rhizobia isolation and characterization.

In this pic, one Bradyrhizobium strain isolated from cowpea root nodule in Brazil showing a "white pearly colony" Read More

1977 H1N1 influenza virus is not relevant to the gain of function debate

The individuals who believe that certain types of gain-of-function experiments should not be done because they are too dangerous (including Lipsitch, Osterholm, Wain-Hobson,) cite the 1977 influenza virus H1N1 strain as an example of a laboratory accident that has led to a global epidemic. A new... Read More

How long have primates been infected with viruses related to HIV?

Disease-causing viruses engage their hosts in ongoing arms races: positive selection for antiviral genes increases host fitness and survival, and viruses in turn select for mutations that counteract the antiviral host factors. Studying such adaptive mutations can provide insights into the distan... Read More

Study: Breastfeeding could reduce common infections among Indigenous infants

TORONTO, Aug. 17, 2015--Promoting breastfeeding could lead to a substantial reduction in common infections and even deaths that are more common in Indigenous infants than non-Indigenous infants, a new study suggests. Read More

Cells in Senescence State May Help Slow down Aging and Cancer Treatment

BOC Sciences-Senescence means a state where cells stop further development in their function but clean themselves and remove the extra substance. Scientists found that when cells go into this stage, the growth rate of tumor would slow down, which is true of aging. The finding was made on the lev... Read More

Chicago!

The skyline of Chicago is depicted here using a bacterial species isolated from human lips. The strain was used to draw the outline of the city on LB agar for several days at room temperature. A wet mount of a colony showed small diplococci and single cells, making this likely to be a species of... Read More

Long Distance Travelers Likely Contributing to Antibiotic Resistance's Spread

Washington, DC – August 20, 2015 - Swedish exchange students who studied in India and in central Africa returned from their sojourns with an increased diversity of antibiotic resistance genes in their gut microbiomes.

Synthetic DNA vaccine against MERS induces immunity in animal study

PHILADELPHIA - A novel synthetic DNA vaccine can, for the first time, induce protective immunity against the Middle East Respiratory Syndrome (MERS) coronavirus in animal species, reported researchers from the Perelman School of Medicine at the University of Pennsylvania. Read More

Expression of a single gene lets scientists easily grow hepatitis C virus in the lab

Worldwide, 185 million people have chronic hepatitis C. Since the late 1980s, when scientists discovered the virus that causes the infection, they have struggled to find ways to grow it in human cells in the lab -- an essential part of learning how the virus works and developing new effective tr...

What's lurking in your lungs? Surprising findings emerge from U-M microbiome research

ANN ARBOR, Mich. -- With every breath you take, microbes have a chance of making it into your lungs. But what happens when they get there? And why do dangerous lung infections like pneumonia happen in some people, but not others? Read More

Toilet waste provides knowledge about diseases' global transmission routes

Current international disease surveillance systems are mainly based on reports made by doctors after treatment of infected patients. As a consequence, disease-causing microorganisms and resistance bacteria have time to spread and make large population groups sick before they are detected. Read More
